The deflection mechanism is adapted to selectively deflect the marking material away from a first path to a second path. A gutter is positioned at an end of the first path, and the solvent free marking material is collected by the gutter. A receiver transporting mechanism is positioned at an end of the second path and the receiver transporting mechanism is adapted to provide a receiver to allow solvent free marking material be deposited on the receiver.
